Technical Field
[0001] The utility model relates to a medical appliance, in particular to an auxiliary tool for blind insertion of a nasointestinal tube. Background Art
[0002] The nasoenteric tube is a commonly used feeding tube in clinical practice. It is inserted through the nasal cavity, passes through the throat, esophagus, stomach and duodenum into the small intestine to provide nutrition to the small intestine so that the human body can obtain sufficient energy. The nasoenteric tube is straightened by a guide wire, and the guide wire is removed after being placed in the stomach. Within 8 to 12 hours, the nasoenteric tube can pass through the pylorus on its own under normal gastrointestinal motility. It can also be provided with nutrients directly from the nasoenteric tube through the pyloric enteral tube with the help of an endoscope to maintain intestinal integrity.
[0003] When a nasogastric tube is blindly inserted from the stomach into the pylorus, the doctor usually bends the nasogastric tube guide wire and uses the index finger to help fix it, so that a certain tension is formed on the tip of the nasogastric tube, and then slowly passes through the pylorus. This operation requires an experienced doctor to complete. It is difficult for novice doctors to master the operation angle and skills, and the success rate is low.
[0004] Therefore, how to design a tool that can assist doctors in completing blind insertion of nasogastric tubes has become an urgent problem to be solved in the field of medical devices. Utility Model Content
[0005] The purpose of the utility model is to provide an auxiliary tool for blind insertion of a nasoenteric tube. The bracket can assist in fixing a bent nasoenteric tube, ensure that the head end of the nasoenteric tube passes through the pylorus smoothly, and improve the success rate of doctors completing the blind insertion of the nasoenteric tube.
[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following two technical solutions:
[0007] Option 1:
[0008] A nasoenteric tube blind insertion auxiliary tool comprises a bracket, the bracket comprises a vertical rod and a horizontal rod, both the vertical rod and the horizontal rod are provided with a tube placement channel, the inner diameter of the tube placement channel is slightly larger than the outer diameter of the nasoenteric tube, a notch is provided on the inner wall of the tube placement channel, the inner diameter of the notch is slightly smaller than the outer diameter of the nasoenteric tube, the vertical rod tube placement channel and the horizontal rod tube placement channel are on the same vertical plane, the nasoenteric tube enters the tube placement channel through the notch, the nasoenteric tube is telescoped in the tube placement channel, and the head end of the nasoenteric tube extends from the horizontal rod tube placement channel and is placed in the patient's nasal cavity.
[0009] Compared with the prior art, the nasointestinal tube blind insertion auxiliary tool using the above technical solution has the following beneficial effects:
[0010] 1. With the utility model of the blind insertion auxiliary tool for nasointestinal tube, the doctor presses the nasointestinal tube into the gap of the vertical pole and the gap of the horizontal pole respectively until the nasointestinal tube enters the tube insertion channel. The inner diameter of the gap is small, so that the nasointestinal tube is limited in the tube insertion channel. The inner diameter of the tube insertion channel is large, so that the nasointestinal tube can be extended and retracted in the tube insertion channel. The vertical pole tube insertion channel and the horizontal pole tube insertion channel respectively fix the two ends of the bending part of the nasointestinal tube, so that a certain tension is formed at the head end of the nasointestinal tube; then hold the vertical pole with one hand and use the other hand to push the nasointestinal tube extending from the vertical pole tube insertion channel, so that the head end of the nasointestinal tube slowly passes through the pylorus. With the assistance of the stent, the success rate of the doctor in completing the blind insertion of the nasointestinal tube can be improved.
[0011] 2. In the preferred solution, a slot is provided between the vertical pole and the horizontal pole, and the bending part of the nasogastric tube is exposed through the slot. While the doctor holds the vertical pole with his hand, he can hold the nasogastric tube at the slot with his index finger, and fine-tune the bending degree of the nasogastric tube according to needs, and assist novice doctors to master the operation angle and skills.
[0012] Preferably, the vertical rod and the horizontal rod are perpendicular to each other and integrally formed, so that the side of the bracket is in an "L" shape. The included angle between the vertical rod and the horizontal rod is a fixed value of 90°, so that a large tension is formed at the head end of the nasogastric tube; the length of the horizontal rod is smaller than the length of the vertical rod, and the "L"-shaped bracket occupies less space, which is convenient for storage and carrying.
[0013] Preferably, a retractable sealing block is provided on the side wall of the notch, and the extended end of the sealing block is inclined at the surface away from the tube placement channel, and the inclined surface of the sealing block is inclined toward the other side wall of the notch.

Both the vertical rod 11 and the horizontal rod 12 are provided with a tube placement channel 14, the inner diameter of the tube placement channel 14 is slightly larger than the outer diameter of the nasoenteric tube 3, and a notch 15 is provided on the inner wall of the tube placement channel 14. The inner diameter of the notch 15 is slightly smaller than the outer diameter of the nasoenteric tube 3. The tube placement channel 14 of the vertical rod 11 and the tube placement channel 14 of the horizontal rod 12 are on the same vertical plane. The nasoenteric tube 3 enters the tube placement channel 14 through the notch 15, and the nasoenteric tube 3 is retracted in the tube placement channel 14. The head end of the nasoenteric tube 3 extends from the tube placement channel 14 of the horizontal rod 12 and is placed in the patient's nasal cavity. The doctor presses the nasointestinal tube 3 into the notch 15 of the vertical pole 11 and the notch 15 of the horizontal pole 12 respectively until the nasointestinal tube 3 enters the tube placement channel 14. The inner diameter of the notch 15 is small, so that the nasointestinal tube 3 is limited in the tube placement channel 14.
